Fire compoent manufacturing process

ABSTRACT

A manufacturing process for a fire component by having a mixture containing expansion graphite powder, chemical fiber and paper fiber at a specific ratio to be bound by a process normally used for the non-woven fabric, and finally hot pressed into sheet, or the mixture is treated as a pulp to be dried for serving as a fire component; accordingly, the process of the present invention gives accurate control of the mixing ratio of the expansion graphite powder and allows to increase the containment of the expansion graphite powder in the fire component up to eighty-five percent (85%), thus to significant upgrade the performance of the fire component.

BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The present invention is related to a manufacturing process for a fire component gives accurate control of the mixing ratio of the expansion graphite powder and allows to increase the containment of the expansion graphite powder in the fire component up to eighty-five percent (85%), thus to significant upgrade the performance of the fire component.

[0003] (b) Description of the Prior Art:

[0004] Expansion graphite power is used as a component in one of the contemporary fire constructional materials. Referring to FIG. 1 of the accompanying drawings, the expansion graphite power (30˜40%) and the ceramic fiberboard (50%+) are alternatively laminated, then dry molded in a structure wherein the expansion graphite power (1) sandwiched by the ceramic fiberboard (2) as illustrated in FIG. 2. Given with the lamination structure, the expansion graphite power (1) when subject to heat in case of a fire will expand for the entire component to fast expand, so to stop the fire from extending and interrupt further diffusion of the smoke.

[0005] However, in the prior art, the expansion graphite powder and the ceramic fiberboard are alternatively laminated, then dry molded; the expansion graphite powder is integrated only with the ceramic fiberboard, instead of the ceramic fiber. Therefore, higher ratio of ceramic fiberboard is required in the component to support the expansion graphite powder that prevents precise control of the ratio of the expansion graphite powder, and further fails increasing the containment of the expansion graphite powder in the component to upgrade its overall fire resisting performance.

SUMMARY OF THE INVENTION

[0006] The primary purpose of the present invention is to provide a process for the manufacturing of a fire component. Wherein, expansion graphite powder, chemical fiber and paper fiber are mixed at a certain ratio, then bound by means of binding process used for the non-woven fabric, then hot pressed into sheet fire component. The process disclosed in the present invention allows accurate control of the mixing ratio of the expansion graphite powder and permits the expansion graphite powder to be integrated with chemical fiber and paper fiber to raise the containment of the expansion graphite powder in the component up to 85% to significantly upgrade its fire performance. Alternatively, the mixture of expansion graphite powder, chemical fiber and paper fiber is treated as a pulp to be dried and molded into a fire component.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Referring to FIG. 3 for a process of the present invention to manufacture a fire component, a mixture containing 50˜85% expansion graphite powder and 10˜50% of chemical fiber and paper fiber is bound by means of that used for the non-woven fabric, the hot pressed at 90˜170° C. for 10˜180 sec. (with the optimal results achieved at 140° C. for 15 sec.) into 0.5˜2 mm thick sheet of fire component. Wherein, the chemical fiber is related to a chemical compound of polyester, PVA or Acrylic.

[0012] As illustrated in FIG. 4, the expansion graphite powder (50˜85%), chemical fiber and paper fiber (10˜50%) are fully mixed in water into pulp, then dried at 150˜200° C. for 20˜200 sec. (with the optimal results achieved at 180° C. for 30 sec.) and finally molded into 0.1˜0.7 mm sheet of fire component.

[0013] Whereas the expansion graphite powder, the chemical fiber and the paper fiber are mixed before being molded into a specific formation in the present invention, it not only allows accurate control of the ratio of expansion graphite powder in the mixture, but also permits the expansion graphite powder to be integrated with both of the chemical fiber and the paper fiber, thus to increase the containment of the expansion graphite powder in the fire component up to 85% to significantly upgrade its overall fire performance.

[0014] The process of the present invention for manufacturing a fire component permits accurate control of containment of the expansion graphite powder in the fire component and increases the containment of the expansion graphite powder in the fire component up to 85%. This application is duly filed accordingly. However, it should be noted that the preferred embodiment is given only for reference purpose and not to limit the present invention.
